Since 2002, we have built seven greenhouses here at the farm. Each and every greenhouse is unique in its design and function since we are always looking for ways to become more efficient and productive. Each time we build a greenhouse we learn…we learn the good and the bad from previous designs. In our newest greenhouse, we’ll call it our Grow-out Greenhouse, we designed it as a sort of experiment to test two different types of filtration systems. It’s Vortex vs. Polygeyser!!
There are 12, 10’ diameter tanks in total. Every set of two tanks is its own system with separate filtration. Three sets of two tanks are using the vortex system and the other three sets of tanks are using the Polygeyser system. The water quality will be tested and recorded routinely, along with feeding amounts. We’ll also record the growth of the koi.
The purpose for using two different filtration systems in the same greenhouse is to compare an “off the shelf” system (Polygeyser) to a system that has been modified and retrofitted (vortex). We are very interested to learn the variances between these two systems and of course, we will fill you in along the way! Keep your eye out for posts with more information on these two systems.
